P TnNT PETER V. HUSTED, OF NEXV YORK, N. Y.

WIRE.

SPECIFICATION forming part of Letters Patent No. 398,259, dated February 19, 1889.

Application filed October 5, 1888. Serial No. 287,272. (No model.)

.To all whom it may concern.-

Ke it known that I, PETER V. HUsTED, a citizen of the United States, and a resident of the city, county, and State of New York, have invented certain new and useful Improvements in 'ire, of which the 'hillowing is a specification.

The object of my invention to produce a new kind oi spirally-threaded wire, in which the spiral is made as nearly as practicable parallel with the length elf the wire. This thread may he a projecting surface running like a spiral ridge along the wire, or it may may he cut out or depressed.

in the acmnnpanying drawings, Figure 1 represents the wire with raised or projecting threml. l ig. 2 is a longitudinal section oi? the die through which the wire has to he drawn to make it of the shape shown in Fig. 1. Fig. i

t represents the wire with the threiul cut into its surface.

Same letiers indieate similar parts in the di tterent figures.

(.t is the body ol' the wire, and is round in cross-section.

Z) is the spiral thread, whichv is made as nearly as praelieahle parallel with the length of the wire.

e is the die, provided with the e "lindrieal channel (I and with the thrmul-eulting channel c. When wire like liig. i3 is to he made. the channel (1 heeonu s a ridge and euis the thread instead ol. raising it.

(onunon ('gvlindrieafl wire, somewhat larger in cross-seetion than lmdyu, isdrawn through i the die e in the usual. method of drawing wire,

and in its passage through said die is forced i to take the form shown in Fig. 1 or Fig. 3, aecording as channel c is raised or depressed in l the die.

By 1isiial."wa l have reference to such drawing-inaehines as that described in Patent No. 364,] 20, dated May Z3] 1887, and granted to \V. A. McCool, and other well-known types of that class in which a grip carried on a carriage seizes the wire and retreats, drawingthe same i through the die. The only change necessary to draw 1n y improved wire on such machines, as will he readil understood by those acquainted with the art of drawing metals, would he to have the grip mounted with antilfrietion hearings, so that the grip might re volve slowl as it retreats in unison with the twist ot the wire, and'thus relieve the latter lfrom all strain cruised by drawing. Of course the grip not. allowed to retreat to a great returned to get a new hold.

The uses and advantages of my improved wire are, I think, suiiieientl obvious, both for making wire nails and spikes, and for other purposes, not to require l'urther explanation.

I elaim A 813iWilly-llll'tttltlttt wi re in which the thread is made nearly parallel with the length of the wire, suhstantially as shown and described.
